Abstract

Differential amplifier with differential outputs comprising a reference input, a signal input, a first (2) and a second (3) low-pass filter connected respectively to a differential output and to an input of a comparator (4), the output of the comparator being connected to the reference input of the amplifier in order to produce a control loop which compensates for the variations in continuous level of the signal applied to the signal input and which drives the difference in the continuous levels of the outputs to a value which tends to zero. <??>Application to integrated circuits with differential amplifiers.
